Our compact size REAL-SOUND AMPLIFIER with Violin-like shaped side panels has progressed towards the next stage. RSA-777EX, its sound is based on the HIGH DEFINITION SOUND of RSA-717EX, contributes to bring you more clear, more natural, and more musical sound.
The basic technologies of this lineup are “Audio class switching power supply” and “CLASS D technology”.
For the RSA-777EX we utilized “HIBIKI-ICHI” capacitors in the “Audio class switching power supply”.
“HIBIKI-ICHI” was developed with the goal of rapid response and natural tone in collaboration with world renowned capacitor manufacturer “NICHICON”. The “HIBIKI-ICHI” brings out even more texture for a more musical sound.
You can see the JAPANESE KANJI on the surface of capacitor. This KANJI is pronounced as “HIBIKI-ICHI”, and ‘’HIBIKI” means vibrancy.
Like a musical instrument maker, we carefully select materials, select the appropriate mechanism of connecting the lumber with the metal chassis, and combine different types of lumber. An amplifier which has a high gain is sensitive to rigidity and vibration, the use of a wooden structure provides suitable vibrational dampening properties. This is precisely why we claim that an amplifier is a musical instrument.
Violin-like shaped wooden panel of RSA-777EX is the structure of sandwiching maple with spruce. Spruce dampen the vibration of chassis suitably and resonated with a music signal like a violin. As you know, “Spruce” is used in string instrument. The 3 dimensional form allows that only Maple supports main body. This design is fundamental in controlling resonance and damping. This brings out the beautiful sound of music. This example of Japanese craftsmanship originates in the historic town “Hida-Takayama”, known for its skilled wood-work and craftsmen.
The myth that a “CLASS D” is a DIGITAL AMPLIFIER is incorrect. SPEC CORP. has adopted “Pulse Width Modulation” in our “CLASS D”. This “PWM” converts “signal amplitude” to “duration switching” through “ANALOG PROCESSING”. This system doesn’t digitize the audio signal. This is in fact type of analog amplifier because magnitude resolution is infinite, same as in an analog amplifier. “CLASS D” with PWM contributes to bring you beautiful acoustical sound. In the past, some audio makers adopted delta sigma modulation for “CLASS D” this is quite simply “1bit digital” modulation.
RSA-777EX has an exclusive amplifier circuit that is designed for headphones. The power supply and Volume Control device are common in main amplifier. You can hear the realistic sound through your headphones in the same manner as same as main amplifier. This construction method creates a pure, realistic output to drive your headphones.
On the belief that “ the joy of music is only found in ‘Real-Sound’”, we have been developing and marketing high-end audio products with the wish of communicating and sharing the sensations, also excitement of our “Real-Sound” music with our customers.
Through High End 2014 in Munich, we will demonstrate four integrated amplifier models including the RSA-F3EX, M3EX, V1EX and 717EX.
With extensive use of latest Class D solutions boosting revolutionary speaker drive power and advanced energy-saving performance these amplifiers deliver beautiful tones and fully dynamic sound, in a word true richness of music someone has never hear before.
And also REQ-S1EX, a phono equalizer amplifier fusing the latest semiconductor technology and matured analog technology, will allow the listeners of analog LP records to rediscover the fascination with “the ultimate high-resolution sound”.
